You are at about F6.4 then. You could stop deepening the curve now if you wish as that's pretty close. With a chordal strike, you often wind up with a deep centre and and edge that lags behind. I suggest you start moving the stroke in towards the centre and start to shorten the stroke. This will help to even up the curve.
I'm assuming you are going for F6 not F5? If you want F5 keep on with the stroke you are using a bit longer.
You can test how good your contact between the tool and mirror are by using the pencil test:
